Transplantation using hematopoietic stem cells (HSCs) has saved the lives of many patients with incurable diseases. Because of its clinical effects, HSCs have been thought to be the cells in the blood that continue to produce all blood cell types throughout life. The identity of HSCs, however, remains surprisingly unexplored due to their rarity (only one in 100,000 mouse bone marrow nucleated cells). In our laboratory, we are tackling this major challenge by using our own unique method that we developed for HSC identification and analyses (https://www.nature.com/articles/nature16943).
We are also actively engaged in joint research and development with research institutions and companies both within Japan and abroad, and are taking on the challenge of opening up new doors in medicine by exploiting the intriguing cytological capabilities of HSCs to their limit.
Research Theme
- Reveal the mechanism underlying HSC-specific function
- Conduct basic research on the age-dependent changes of hematopoietic function
- Develop novel transplantation method
- Develop novel methods for using HSC
- Translational research through collaborations with external organizations
